A novel drying equipment for producing high-calorific-value biomass pellets

Abstract

This utility model relates to the field of biomass pellet drying technology, specifically, to a novel drying device for producing high-calorific-value biomass pellets. It includes a base plate, with support feet fixedly connected to the four corners of the bottom side of the base plate, and a rectangular hole in the center of the top side of the base plate. Since the high-calorific-value biomass pellets may mold if not dried, this utility model addresses this issue by fixing a drive motor to the center of one side of the base plate. The output shaft of the drive motor is fixedly connected to one end of a rotating shaft. The drive motor drives two trapezoidal cages to rotate within the housing via the rotating shaft and two rotating tubes, thereby stirring the high-calorific-value biomass pellets within the cages. Simultaneously, under the action of two drying components, the high-calorific-value biomass pellets within the cages are baked, thus achieving the drying process.

Description

Technical Field

[0001] This utility model relates to the field of biomass pellet drying technology, specifically, to a novel drying equipment for producing high-calorific-value biomass pellets. Background Technology

[0002] As the global energy structure shifts towards a greener approach, biomass pellets, as a clean and renewable energy source, are increasingly being used in heating, power generation, and other fields due to their high combustion efficiency and low pollution characteristics. Under the dual pressures of the energy crisis and climate change, the carbon emissions from the use of traditional fossil fuels are becoming increasingly severe, prompting many countries around the world to set carbon neutrality targets. Biomass energy, as a renewable resource capable of achieving carbon cycling, is ushering in unprecedented development opportunities.

[0003] Currently, during the production of new high-calorific-value biomass pellets, the pellets themselves contain a large amount of moisture. If the pellets are not dried, they may become moldy, affecting combustion efficiency and making storage difficult. Therefore, a drying device for the production of new high-calorific-value biomass pellets is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a novel drying device for producing high-calorific-value biomass pellets, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a novel drying device for producing high calorific value biomass pellets, comprising a base plate, with support feet fixedly connected to the four corners of the bottom side of the base plate, a rectangular hole opened in the middle of the top side of the base plate, a shell fixedly connected inside the rectangle, sliding holes opened in the middle of both sides of the shell, and drying components fixedly installed on the inner walls of both sides of the shell, with the two drying components located at the top of the two sliding holes;

[0006] The housing is provided with a flipping assembly, which includes a rotating shaft. Rotating holes are provided at the middle of the other two sides of the housing. The two ends of the rotating shaft are respectively rotatably connected to the two rotating holes. Two rotating tubes are slidably connected to the outside of the rotating shaft, and the two rotating tubes are arranged far apart from each other. A truncated cage is fixedly connected to the outside of each of the two rotating tubes.

[0007] As a further improvement to this technical solution, the outer sides of the two platform-shaped cages are rotatably connected to docking circular bars at positions away from the two rotating tubes, and the two docking circular bars are used to dock the two platform-shaped cages. One of the platform-shaped cages is fixedly connected to an injection pipe near the middle position on its outer side, and the injection pipe is connected to the interior of the platform-shaped cage.

[0008] As a further improvement to this technical solution, rotating rings are rotatably connected to the outer sides of the two platform-shaped cages near the positions away from the two rotating tubes. Two hinge bars are fixedly connected to the outer sides of the two rotating rings. The two hinge bars are arranged symmetrically. The two hinge bars on the outer side of one rotating ring are slidably connected to two sliding holes, while the two hinge bars on the outer side of the other rotating ring are fixedly connected to two sliding holes.

[0009] As a further improvement to this technical solution, a telescopic cylinder is hinged between two hinge bars corresponding to the outer sides of the two rotating rings. The two telescopic cylinders drive one of the platform-shaped cages to slide on the outer side of the rotating shaft through multiple hinge bars and the two rotating rings.

[0010] As a further improvement to this technical solution, a drive motor is fixedly installed at the middle position on one side of the substrate. The output shaft of the drive motor is fixedly connected to one end of the rotating shaft. The drive motor drives two truncated cages to rotate inside the housing through the rotating shaft and two rotating tubes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In the drying equipment for producing new high-calorific-value biomass pellets, failure to dry the pellets may lead to mold growth. A drive motor is fixedly installed at the center of one side of a base plate. The output shaft of the drive motor is fixedly connected to one end of a rotating shaft. The drive motor drives two platform-shaped cages to rotate within the housing via the rotating shaft and two rotating tubes. This causes the high-calorific-value biomass pellets to be stirred within the cages. Simultaneously, under the action of two drying components, the high-calorific-value biomass pellets within the cages are baked, thus achieving the drying process. Attached Figure Description

[0020] Example 1

[0021] Please see Figures 1-3 As shown, this embodiment provides a novel drying device for producing high-calorific-value biomass pellets, including a base plate 1. Support feet are fixedly connected to the four corners of the bottom side of the base plate 1. The multiple support feet can support the drying device and prevent it from moving during operation. A rectangular hole is opened in the middle of the top side of the base plate 1, and a shell 2 is fixedly connected inside the rectangle. The rectangular hole ensures that the shell 2 is fixedly connected to the base plate 1. Sliding holes 3 are opened in the middle of both sides of the shell 2. Drying components 4 are fixedly installed on the inner walls of both sides of the shell 2, and the two drying components 4 are located at the top of the two sliding holes 3. The two drying components 4 can heat the inside of the shell 2.

[0022] The housing 2 is equipped with a flipping component 5, which can rotate the new high-calorific-value biomass pellets, facilitating the roasting of the pellets by the two drying elements 4, thereby achieving the drying effect of the high-calorific-value biomass pellets. It also facilitates material discharge. The flipping component 5 includes a rotating shaft 51, and rotating holes are provided at the middle of both sides of the housing 2. The two ends of the rotating shaft 51 are rotatably connected to the two rotating holes, which limit the movement of the two ends of the rotating shaft 51, ensuring that the rotating shaft 51 can rotate within the housing 2. Two rotating tubes 52 are slidably connected to the outer side of the rotating shaft 51, and the two rotating tubes 52 are arranged far apart from each other. A truncated cage 53 is fixedly connected to the outer side of each of the two rotating tubes 52. Through the rotating tubes 52, one of the truncated cages 53 can slide on the outer side of the rotating shaft 51. A drive motor 59 is fixedly installed in the middle of one side of the base plate 1. The output shaft of the drive motor 59 is fixedly connected to one end of the rotating shaft 51. The drive motor 59 drives the two truncated cages 53 to rotate in the shell 2 through the rotating shaft 51 and the two rotating tubes 52, thereby enabling the new high calorific value biomass pellets to be turned over.

[0023] Please see Figures 1-3 As shown, two platform cages 53 are rotatably connected to the outer sides of the two rotating tubes 52 at positions away from the two rotating tubes 52. The two docking circular bars 54 are used to dock the two platform cages 53, avoiding direct docking of the two platform cages 53 and causing damage to the two platform cages 53. One of the platform cages 53 is fixedly connected to the outer side near the middle position with a material injection pipe 55, and the material injection pipe 55 is connected to the inside of the platform cage 53. The material injection pipe 55 facilitates the workers to inject materials.

[0024] Please see Figures 1-3 As shown, rotating rings 56 are rotatably connected to the outer sides of the two platform-shaped cages 53, near and away from the two rotating tubes 52. Two hinge bars 57 are fixedly connected to the outer sides of each rotating ring 56. The two hinge bars 57 are symmetrically arranged. The two hinge bars 57 on the outer side of one rotating ring 56 are slidably connected to two sliding holes 3, and the two hinge bars 57 on the outer side of the other rotating ring 56 are fixedly connected to two sliding holes 3. Telescopic cylinders 58 are hinged between the two corresponding hinge bars 57 on the outer sides of the two rotating rings 56. The two telescopic cylinders 58 drive one of the platform-shaped cages 53 to slide on the outer side of the rotating shaft 51 through the multiple hinge bars 57 and the two rotating rings 56, so that the two platform-shaped cages 53 move away from each other, thereby discharging the new high-combustion-value biomass pellets inside the two platform-shaped cages 53.

[0025] In practical use, the drying equipment for producing novel high-calorific-value biomass pellets in this embodiment first connects the power supply to the drying equipment. The novel high-calorific-value biomass pellets are then injected into two platform-shaped cages 53 through the feeding pipe 55. A drive motor 59 is fixedly installed at the middle position of one side of the base plate 1. The output shaft of the drive motor 59 is fixedly connected to one end of the rotating shaft 51. The drive motor 59 drives the two platform-shaped cages 53 to rotate within the housing 2 through the rotating shaft 51 and two rotating pipes 52, thereby stirring the novel high-calorific-value biomass pellets in the two platform-shaped cages 53. At the same time, under the action of the two drying components 4, the novel high-calorific-value biomass pellets in the two platform-shaped cages 53 can be baked. After the novel high-calorific-value biomass pellets are dried, two telescopic cylinders 58 drive one of the platform-shaped cages 53 to slide outside the rotating shaft 51 through multiple hinge bars 57 and two rotating rings 56, so that the two platform-shaped cages 53 move away from each other, thereby discharging the novel high-calorific-value biomass pellets in the two platform-shaped cages 53.
